Try uMatrix: https://github.com/gorhill/uMatrix https://github.com/gorhill/uMatrix Super simple web connection switchboard by Gorhill (person behind uBlock Origin). It allows you to assign certain addresses and elements to block calls from/to. For example 'www.google-analytics.com'. I use it as a catch-all when loading a web page, then release elements that I want to load.
